The device of the present invention comprises means for connection to a patient, wherein said means are made in the shape of a respiratory tube (6) that extends outwardly from an outer vessel (1) and is connected to systems for generating a resistance against the air flow. The resistance-generating systems are made in the shape of an inner chamber (7) that comprises openings (8) in its lower section and is mounted in an intermediate vessel (9) with an upward opening (12) for communication with the medium in the outer vessel (1). The outer vessel is fitted with atmospheric-air inlet systems in the shape of opened apertures (4). The device further includes means for separating the portion of the outer vessel (1) functional volume, wherein said means are made in the shape of a transversal baffle (13) which is capable of axial displacement and can be fixed. The baffle rests against the inner surface of the outer vessel (1) and against the outer surface of the intermediate vessel (9). |
